Swing Vibrating Screen-DAHAN Vibration Machinery

What is an Swing Vibrating Screen?

Swing vibrating screen is an effective principle of simulating the motion of artificial screening at present. It has rotating and swinging vibration. The particles of different sizes are screened through different layers of screens and then discharged from different outlets. The screening accuracy is as high as 95%. Above, the efficiency is super high, the life of the screen is more than 3 times that of conventional screening equipment, and the output is also 3-5 times that of ordinary screening equipment. Compatible with all fine and ultra-fine ranges of powder and particulate materials, especially suitable for difficult to handle and high-volume materials.

Types of Swing Vibrating Screen

Circular Swing Vibrating Screen

Imitating manual screening, materials will be shaken and scattered on the screen and thrown upward and downward slightly. The screening efficiency is generally 93% to 95%. It is suitable for a variety of applications, including classification, exfoliation and dehydration.

Square Swing Vibrating Screen

The reciprocating rotary motion quickly disperses materials. It adopts a multi-layer "duplex" design, allowing one to be used in multiple vibrating screens, which is several times the processing capacity of traditional vibrating screens.

Material classifications of swing vibrating screen

Allstainless steel swing vibrating screen: Made of stainless steel, it has the advantages of corrosion resistance and easy cleaning. It is suitable for industries with high hygiene requirements such as food and medicine.

Contact part stainless steel swingvibrating screen: Contact part of the vibrating screen is made of stainless steel, such as screen mesh, screen frame, etc., while other non-contact parts are made of carbon steel or other materials. It is suitable for occasions where product hygiene requirements are high but costs need to be reduced.

Allcarbon steel swing vibrating screen: Made of carbon steel, it has high strength and wear resistance and is suitable for general industrial fields. The price is relatively low and suitable for use in situations where material requirements are not high.

Working Principle of Swing Vibrating Screen

The swing vibrating screen works by using a motor to drive the screen surface back and forth in a circular motion. This motion causes the material on the screen surface to move in a spiral pattern. As the material moves, the smaller particles fall through the screen openings, while the larger particles are conveyed to the discharge end of the screen.

The swing motion of the screen helps to prevent particles from sticking to the screen surface. This is because the particles are constantly being lifted and moved around, which prevents them from forming a bond with the screen.

Benefits of Swing Vibrating Screen

High screening efficiency

Effectively imitating the action and process of manual screening, the material presents an involute spiral trajectory on the screen surface, making the material travel a relatively long distance on the relative area, achieving 6-level separation, and the screening accuracy is as high as 90%-95 %.

High yield

Soft rock screening, no high-speed vibration, no damage to the original particle structure of the material, not easy to generate static electricity, more suitable for screening flammable, explosive and easy to generate static electricity materials.

The mesh is not clogged

Bouncing ball, ultrasonic wave, and drum brush are optional cleaning devices. Various anti-blocking technologies make the sieve holes not easy to block, which is beneficial to improve screening accuracy and screening output.

Multi-layer screening

The effective screening area of each layer is 0.28-6.4㎡, up to 5 layers can be used, and it can provide grading of 6 kinds of products with different specifications.

Long lasting

Working with low frequency and small load, the acceleration is 4-5 times lower than that of the vibrating screen, which makes the screen not easy to damage and prolongs the service life of the screen.

Low working noise

Internal sealing, airtightness up to 50 mPa, rubber tension spring left and right tension support, good shock absorption and buffering effect, working noise as low as 75 decibels.

Difference Between Swing Vibrating Screen and Ordinary Vibrating Screen

Swing Vibrating Screen	Ordinary Vibrating Screen
Elliptical Swing (simulates artificial)	High-speed vibrating screening material
no damage material	Potential to destroy material
Accuracy up to 95%	Accuracy 50%-95% (different materials)
Less wear and tear without beating	Beating the screen surface, the screen mesh is greatly worn

1. The Swing vibrating screen is more suitable for irregular or wet materials within 500 mesh due to the artificial screening and the addition of a net cleaning device, which overcomes the risk of blocking the screen of ordinary vibrating screens, and the vibrating screen belongs to unbalanced damage. Violent movement uses the principle of vibration to screen materials, so sometimes the materials are destroyed. Therefore, for some ">granular crystals and brittle materials, it is recommended to use swing screen, and its screening accuracy can reach more than 95%.

2. For the materials above 30 mesh, the output of the vibrating screen and the swing vibrating screen are basically the same. For the raw materials from 30 mesh to 500 mesh, the output of the swing screen is much higher than that of the vibrating screen, which is generally a vibrating screen. 5-10 times.

Structure of Swing Vibrating Screen

Product features

The key components of a swing vibrating screen include:

Screen Frame: This is the rigid structure that supports the screen mesh. It is typically made of steel and can be designed in various shapes depending on the application.

Screen Mesh: This is the surface that separates the particles. The mesh can be made of woven wire, perforated plate, or other materials, and the size of the openings will determine the size of the particles that can pass through.

Vibration Motor: This is the motor that creates the swinging motion of the screen. The motor is usually mounted on the underside of the screen frame and is connected to an unbalanced shaft. As the shaft rotates, it creates a centrifugal force that causes the screen to swing back and forth.

Shock Absorber Springs: These springs are used to isolate the vibration of the screen from the surrounding structure. They also help to control the amplitude of the swing motion.

Transmission Device: This device transmits the vibration from the motor to the screen frame. It can be a simple shaft or a more complex mechanism, such as a gear drive.

Here's an additional component you might find in some designs:

Dust Cover: This optional cover helps to contain dust and debris generated during the screening process.

Screen mesh cleaning device

During the screening process, due to the strong adsorption, easy agglomeration, high electrostatic properties, strict requirements on accuracy, high density and light weight of various materials, it is easy to cause screen clogging, thereby significantly reducing screening efficiency. Therefore, it becomes crucial to add a screen cleaning device to the equipment. Combining many years of screening manufacturing experience, we have developed a variety of screen cleaning devices based on the needs of different materials.

Ball Cleaning System: Small balls are placed in a separate chamber and vibrate against the screen, dislodging any stuck particles.

Kleener System: Small scraper blades move across the underside of the screen, scraping away any buildup.

Brush System: Rotating brushes sweep across the screen surface, removing any particles that might clog the mesh.

Ultrasonic System (less common): High-frequency sound waves vibrate the mesh, dislodging particles without physical contact.
